Patent DK-59987-A (DK)
Inventor: PALM MICHIEL
IPC: H02H9/06
Filed: 1987-02-05
Abstract: Device for establishing such a galvanic connection between conductors of a first batch and conductors of a second batch that on the one hand signal transmission between the two batches can take place undisturbed, and on the other hand transmission consequent on inducing electro-magnetic radiation will be blocked in two respects. High voltage induced in the conductors of the first batch consequent on high-energetic radiation, which manifests itself as a pulse, is reduced in stages to a relatively low residual voltage on the conductors of the second batch. Besides voltages induced either in the conductors of the first batch or in the conductors of the second batch, consequent on electromagnetic radiation having a signal character, are strongly reduced, in such a way that the conductors of the relevant other batch (either the second or the first) will not cause a detectable corresponding radiation. For that purpose an LD-filter configuration with one or two T-sections connected in cascade has been connected between each pair of corresponding conductors. In one of these T-sections a coil, which also forms part of a high- voltage reducing section, has been utilized. The device is mounted in a housing, which blocks electromagnetic radiation and can be fixed to a wall of a Faraday cage room in such a way that an opening in that wall will be closed. In this manner electric conductors extending to the interior of the Faraday cage room can be connected, in the desired way, to electric conductors establishing a connection with the outer world.

Title: Improvements in or relating to circuits for television receivers
IPC: H04B14/08
Filed: 1955-01-06
Abstract: 783,597. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 6, 1955 [Jan. 6, 1954], No. 451/55. Class 40 (3). [Also in Group XL (c)] In a television transmission system in which two vision signals are simultaneously transmitted by asymmetrically amplitude modulating the positive and negative half-cycles respectively of a sub-carrier which modulates the main carrier, demodulation of the sub-carrier is effected by two independent tuned circuits feeding biased diodes of opposite polarity. The output of an R.F. or L.F. amplifier 11 is coupled by capacitors 13<SP>1</SP>a and 13<SP>11</SP>a to a tuned circuit comprising capacitor 12 and inductor 13a, and is also coupled by capacitors 13<SP>1</SP>b, 13<SP>11</SP>b to a tuned circuit 12, 13b. The first circuit 12, 13a supplies a diode 14a which is biased via decoupling network 16a so as to conduct only on those parts of the positive half-cycles of carrier that correspond to the positive halfcycles of sub-carrier, i.e. above an amplitude corresponding to zero sub-carrier. This first signal is passed via diode 17a to a load resistor 18a. The second circuit 12, 13b supplies a diode 14b which is biased via decoupling network 16b so as to conduct on those parts of the negative half cycles of carrier that correspond to the negative half-cycles of sub-carrier, i.e. having an amplitude between the levels corresponding to zero carrier and zero sub-carrier. This second signal is passed via diode 17b to a load 18b. Various conventional synchronizing pulse separators, e.g. diode 19 and pentode limiters, Figs. 3 and 4 (not shown), are added. It is stated that the two signals may represent two separate monochrome transmissions, the stereoscopic components of a single image or may be the red and green components of a colour television system in which case they may be added to form the luminance signal which controls a monochrome C.R. tube. Specification 779,287 is referred to.
